Issues in deploying a web application on WASCE

This issue is causing a lot of problems.I would be extremely grateful if anyone could suggest something,in this regard:

Last night after installing WASCE on my Ubuntu 12.04,I decided to deploy a web app to test it.I made a folder inside the home directory(lets call it "Web Application").Inside it I made a test.html file and WEB-INF folder.Inside the WEB-INF directory,I created the web.xml and geronimo-web.xml(that specified the context root as /abc and welcome page as "test.html")
But when I open my browser to vist "http://localhost:8080/abc",I get a 404 Not Found,though WASCE is rightly installed(I checked the installation by visiting http://localhost:8080).Where am I going wrong?
